Members BoredGuitarist7 Posted February 17, 2009 Members Share Posted February 17, 2009 (Fab Distortion and Cool Cat Distortion) Do I just wire the output from the first pedal to the input of the other pedal? And then, when I bypass one, it will go through the buffer and to the input of the other pedal, through the components and out to the amp? Link to comment Share on other sites More sharing options...
Members H.R. Shove and Stuff Posted February 17, 2009 Members Share Posted February 17, 2009 Pretty much, yep. Tip of output goes to tip of input. Exact same way a patch cable works. Link to comment Share on other sites More sharing options...

Members SUPER VELCROBOY Posted February 17, 2009 Members Share Posted February 17, 2009 wire the pedals in paralle for power should add decoupling Link to comment Share on other sites More sharing options...
Members musikerochan Posted February 17, 2009 Members Share Posted February 17, 2009 should add decoupling what decoupling? how? isnt it that you just daisy chain the pedals from a single source (provided the current draw is not more than the total supplied by the PSU)?

Members BoredGuitarist7 Posted February 17, 2009 Author Members Share Posted February 17, 2009 Someone mind MS Painting the joining of the two power supplies to both units? Which wires goes to which lugs on the DC jack? Link to comment Share on other sites More sharing options...

Which wires goes to which lugs on the DC jack? Just wire it like you normally would, except each lug will have two wires instead of one. Link to comment Share on other sites More sharing options...
Members ShortScaleMike Posted February 17, 2009 Members Share Posted February 17, 2009 Some pretty shocking advice in this thread. You should decouple the power supplies from each other. Wire two 100 ohm resistors from your +9V input, one to each pedal power in, and drop a 47uF cap to ground from the power input to each pedal also.

Members NITEFLY182 Posted February 17, 2009 Members Share Posted February 17, 2009 If you're wondering what decoupling actually does read this article. http://www.electronicpeasant.com/circuits/decouple.txt It will help you understand what everyone is saying and give you some extra info.

Members BoredGuitarist7 Posted February 17, 2009 Author Members Share Posted February 17, 2009 Ok. This is my first dual pedal type deal. I am still a little bit confused.I'd wire the pedals power supply portion of the PCB to the positive sleeve of the DC Jack, with a 100 ohm resistor in its path. The 47uf capacitors go where in relation to the circuit? Thanks for the responses. Gave that decoupling explanation read, Nitefly, and I understand the purpose for it more now. Now that I think about it, I wouldn't be able to use two 9v to power the pedals. Since the Fab Distortion will always have the input jack wired to the Cool Cat Distortion, the battery power supply would never be bypassed and it'd just drain. Fast.

Members andreas Posted February 17, 2009 Members Share Posted February 17, 2009 Adding decoupling on the power feeds to each of the circuits is a good idea. When stuffing more than one home-made circuit in a box, it would be essential. However, this should already be done in the circuits themselves (as they are designed to work off a daisy-chain cable). But have a look at where the +9v ends up in each pedal - if they don't have that extra 100ohm (or so) resistor, adding them to the feed from the common DC input jack should help.

Fast. 9V at DC jack -> 100 ohm resistor -> circuit 9v and also a 47uF cap to ground. Link to comment Share on other sites More sharing options...
